Objective: The main objective of this research is to explain the accrual anomaly using accruals factor (CMA) and accrual-based factor-mimicking portfolios as well as checking whether accrual anomaly is risk-based or mispricing. According to rational frictionless asset pricing model, the ability of accruals to predict returns should come from the loadings on this accrual factor loading that pred...

We estimate the relative roles of factor inputs and productivity in explaining the level of economic development, which is measured as output per worker. For a large sample of countries, we show that alternative identifying productivity assumptions and alternative measures of human capital have a large impact on the relative weights of factor inputs and productivity in a decomposition of output...

Abstract: Energy intensity is a measure of the energy efficiency of a nation’s economy. Many factors influence a country’s energy intensity. In this paper, however, we note the effective factors of energy intensity and decompose it by applying Logistic Smooth Transition Regression (LSTR) in Iran during the period 1980- 2013. The main factors are the ratio of the added value of se...
